Healthcare resource utilisation and costs in patients with treated obstructive sleep apnea

Obstructive sleep apnea (OSA) is a highly prevalent yet underdiagnosed disease that creates a large economic burden on the United States healthcare system. In this retrospective study, we tested the hypothesis that adherence to positive airway pressure (PAP) therapy, the 'gold standard' treatment for OSA, is associated with reduced healthcare resource utilisation and costs. We linked de-identified payer-sourced medical claims and objective PAP usage data for patients newly diagnosed with OSA. Inverse probability of treatment weighting was used to create balanced groups of patients who were either adherent, intermediately adherent, or non-adherent to PAP therapy. From a sample of 179,542 patients (average age 52.5 years, 61% male), 37% were adherent, 40% intermediate, and 23% non-adherent. During the first year, PAP adherence was significantly associated with fewer emergency room visits (mean [SD] adherent: 0.39 [1.20] versus intermediate: 0.47 [1.30], p < 0.001; versus non-adherent: 0.54 [1.44], p < 0.001), all-cause hospitalisations (mean [SD] adherent: 0.09 [0.43] versus intermediate: 0.12 [0.51], p < 0.001; versus non-adherent: 0.13 [0.55], p < 0.001), and lower total costs (mean [SD] adherent $5874 [8045] versus intermediate $6523 [9759], p < 0.001; versus non-adherent $6355 [10,517], p < 0.001). Results were similar in the second year of PAP use. These results provide additional evidence from a large, diverse sample to support the diagnosis and treatment of OSA and encourage long-term adherence to PAP therapy.

Healthcare resource utilisation and economic burden of patients with adequate and inadequate responses to biological and targeted synthetic disease-modifying antirheumatic drugs for rheumatoid arthritis in Japan

OBJECTIVE

To compare healthcare resource utilisation (HCRU) and direct costs between responders vs non-responders to advanced therapies for rheumatoid arthritis (RA).

METHODS

Patients initiating ≥1 advanced therapy (Oct 2018-Sept 2019) with ≥1 RA claim (6-month pre-index period), ≥2 RA claims (any period), and ≥12 months follow-up were identified from the Medical Data Vision claims database. HCRU and all-cause and RA-related costs (direct medical, emergency department [ED], laboratory, and pharmacy) were compared between responders vs non-responders. Adjusted incidence rate ratios (IRRs) for HCRU or cost were calculated via multivariable analyses.

RESULTS

Among 2,446 patients (non-responders [n=1,817]; responders [n=629]), non-responders had significantly longer hospitalisation days (IRR: 1.8 [95% CI: 1.2-2.6]), and significantly more ED visits (2.5 [1.5-4.2]) and prescriptions (1.1 [1.1-1.2]). Mean all-cause hospital/outpatient medical costs were significantly higher for non-responders (1.4 [1.3-1.6], ¥530,895 vs ¥357,009 [$;3,992 vs $;2,684] for responders; ¥173,886 [$;1,307] difference); RA-related medical costs showed a similar trend (¥351,306 vs ¥253,030 [$;2,641 vs $1,902]; ¥98,276 [$;739] difference). No differences between responders and non-responders were observed in mean all-cause and RA-related pharmacy costs.

CONCLUSIONS

Non-responders to advanced therapies had greater HCRU and all-cause/RA-related direct costs as compared with responders, suggesting a need for more effective RA therapies to reduce the economic burden associated with non-response.

Real-world characterisation of patients with chronic rhinosinusitis with nasal polyps with and without surgery in England

OBJECTIVES

To characterise the real-world burden of chronic rhinosinusitis with nasal polyps (CRSwNP) in the UK, stratified by number of surgeries.

DESIGN

Retrospective cohort study.

SETTING

UK Clinical Practice Research Datalink Aurum database with Hospital Episodes Statistics linkage (2007-2019).

PARTICIPANTS

Adults ≥18 years of age with a first NP diagnosis (index) and 365 days of baseline and ≥180 days of follow-up data. Follow-up continued until disenrollment, death or end of data collection.

MAIN OUTCOME MEASURES

Primary: primary care physician prescribed CRSwNP-related treatments, and all-cause healthcare resource utilisation (HCRU) in 90 days post-index, stratified by surgeries during follow-up. Secondary: rate of surgery and CRSwNP point prevalence. Baseline patient demographics, clinical characteristics and comorbidities were also assessed.

RESULTS

Of the 33 107 patients included, 23.5% and 2.2% had ≥1 and ≥2 surgeries during follow-up, respectively (mean follow-up: 5.3 years). Patients with more surgeries (≥2/≥1/0) during follow-up were more likely to be male (67.3%/69.0%/58.0%), have asthma (37.8%/28.2%/20.2%) and have baseline blood eosinophil counts ≥300 cells/μL (68.5%/66.0%/51.5%). During the first 90-days post-index as surgery number increased, the proportion of patients using oral corticosteroids (25.8%/20.7%/14.2%) and mean (SD) number of all-cause healthcare visits (5.9 [4.2]/5.4 [4.0]/4.9 [4.2]) increased. Time between surgeries was shorter among patients with more surgeries. CRSwNP prevalence on 31 December 2018 was 476 cases per 100 000 persons.

CONCLUSION

A small proportion of patients in the UK required multiple surgeries for CRSwNP and this was associated with increasing comorbidity burden, baseline blood eosinophil counts, CRSwNP-related treatment and HCRU use.

Real-world analysis of patients with haemophilia A and haemophilia A carriers in the United States: Demographics, clinical characteristics and costs

INTRODUCTION

Females with haemophilia A (HA [FHAs]) and HA carriers (HACs) have an increased risk of bleeding and complications compared to the general population.

AIM

To examine the characteristics, billed annualised bleed rates (ABRb ), costs and healthcare resource utilisation for males with HA (MHAs), FHAs and HACs in the United States.

METHODS

Data were extracted from the IBM® MarketScan® Research Databases (Commercial and Medicaid) for claims during the index period (July 2016 to September 2018) and analysed across MHAs, FHAs and HACs.

RESULTS

Dual diagnosis females (DDFs; both HA and HAC claims) were grouped as a separate cohort. MHAs were generally younger than females (all cohorts) by up to 19 years (Commercial) and 23 years (Medicaid). ABRb  >0 was more frequent in females. Factor VIII claims were higher for MHAs versus female cohorts. Joint-related health issues were reported for 24.4 and 25.6% (Commercial) and 29.3 and 26.6% (Medicaid) of MHAs and FHAs, respectively; lower rates were reported in the other two cohorts. Heavy menstrual bleeding claims occurred for approximately a fifth (Commercial) to a quarter (Medicaid) of female cohorts. All-cause emergency department and inpatient visits in FHAs and DDFs were similar to, or more frequent than, those in MHAs; bleed-related inpatient visits were infrequent. In MHAs (Commercial), mean all-cause total costs ($214,083) were higher than in FHAs ($40,388), HACs ($15,647) and DDFs ($28,320) with similar trends for Medicaid patients.

CONCLUSIONS

FHAs and HACs may be undermanaged and undertreated. Further research is needed to fully understand these cohorts' bleeding rates, long-term complications and costs.

Patterns of Healthcare Resource Utilisation of Critical Care Survivors between 2006 and 2017 in Wales: A Population-Based Study

In this retrospective cohort study, we used the Secure Anonymised Information Linkage (SAIL) Databank to characterise and identify predictors of the one-year post-discharge healthcare resource utilisation (HRU) of adults who were admitted to critical care units in Wales between 1 April 2006 and 31 December 2017. We modelled one-year post-critical-care HRU using negative binomial models and used linear models for the difference from one-year pre-critical-care HRU. We estimated the association between critical illness and post-hospitalisation HRU using multilevel negative binomial models among people hospitalised in 2015. We studied 55,151 patients. Post-critical-care HRU was 11-87% greater than pre-critical-care levels, whereas emergency department (ED) attendances decreased by 30%. Age ≥50 years was generally associated with greater post-critical-care HRU; those over 80 had three times longer hospital readmissions than those younger than 50 (incidence rate ratio (IRR): 2.96, 95% CI: 2.84, 3.09). However, ED attendances were higher in those younger than 50. High comorbidity was associated with 22-62% greater post-critical-care HRU than no or low comorbidity. The most socioeconomically deprived quintile was associated with 24% more ED attendances (IRR: 1.24 [1.16, 1.32]) and 13% longer hospital stays (IRR: 1.13 [1.09, 1.17]) than the least deprived quintile. Critical care survivors had greater 1-year post-discharge HRU than non-critical inpatients, including 68% longer hospital stays (IRR: 1.68 [1.63, 1.74]). Critical care survivors, particularly those with older ages, high comorbidity, and socioeconomic deprivation, used significantly more primary and secondary care resources after discharge compared with their baseline and non-critical inpatients. Interventions are needed to ensure that key subgroups are identified and adequately supported.

Clinical and economic burden of pneumococcal disease among individuals aged 16 years and older in Germany

This study assessed the incidence rate of all-cause pneumonia (ACP) and invasive pneumococcal disease (IPD) and associated medical costs among individuals aged ≥16 in the German InGef database from 2016 to 2019. Incidence rate was expressed as the number of episodes per 100 000 person-years (PY). Healthcare resource utilisation was investigated by age group and by risk group (healthy, at-risk, high-risk). Direct medical costs per ACP/IPD episode were estimated as the total costs of all inpatient and outpatient visits. The overall incidence rate of ACP was 1345 (95% CI 1339-1352) and 8.25 (95% CI 7.76-8.77) per 100 000 PY for IPD. For both ACP and IPD, incidence rates increased with age and were higher in the high-risk and at-risk groups, in comparison to the healthy group. ACP inpatient admission rate increased with age but remained steady across age-groups for IPD. The mean direct medical costs per episode were €8075 (95% CI 7121-9028) for IPD and €1454 (95% CI 1426-1482) for ACP. The aggregate direct medical costs for IPD and ACP episodes were estimated to be €8.5 million and €248.9 million respectively. The clinical and economic burden of IPD and ACP among German adults is substantial regardless of age.

Intraoperative hypotension is associated with persistent acute kidney disease after noncardiac surgery: a multicentre cohort study

BACKGROUND

Whilst intraoperative hypotension is associated with postoperative acute kidney injury (AKI), the link between intraoperative hypotension and acute kidney disease (AKD), defined as continuing renal dysfunction for up to 3 months after exposure, has not yet been studied.

METHODS

We conducted a retrospective multicentre cohort study using data from noncardiac, non-obstetric surgery extracted from a US electronic health records database. Primary outcome was the association between intraoperative hypotension, at three MAP thresholds (≤75, ≤65, and ≤55 mm Hg), and the following two AKD subtypes: (i) persistent (initial AKI incidence within 7 days of surgery, with continuation between 8 and 90 days post-surgery) and (ii) delayed (renal impairment without AKI within 7 days, with AKI occurring between 8 and 90 days post-surgery). Secondary outcomes included healthcare resource utilisation for patients with either AKD subtype or no AKD.

RESULTS

A total of 112 912 surgeries qualified for the study. We observed a rate of 2.2% for delayed AKD and 0.6% for persistent AKD. Intraoperative hypotension was significantly associated with persistent AKD at MAP ≤55 mm Hg (hazard ratio 1.1; 95% confidence interval: 1.38-1.22; P<0.004). However, IOH was not significantly associated with delayed AKD across any of the MAP thresholds. Patients with delayed or persistent AKD had higher healthcare resource utilisation across both hospital and intensive care admissions, compared with patients with no AKD.

CONCLUSIONS

Intraoperative hypotension is associated with persistent but not delayed acute kidney disease. Both types of acute kidney disease appear to be associated with increased healthcare utilisation. Correction of intraoperative hypotension is a potential opportunity to decrease postoperative kidney injury and associated costs.

Disease burden and economic impact of diagnosed non-alcoholic steatohepatitis in five European countries in 2018: A cost-of-illness analysis

BACKGROUND AND AIMS

Non-alcoholic steatohepatitis (NASH) is a chronic disease that can progress to end-stage liver disease (ESLD). A large proportion of early-stage NASH patients remain undiagnosed compared to those with advanced fibrosis, who are more likely to receive disease management interventions. This study estimated the disease burden and economic impact of diagnosed NASH in the adult population of France, Germany, Italy, Spain and the United Kingdom in 2018.

METHODS

The socioeconomic burden of diagnosed NASH was estimated using cost-of-illness methodology applying a prevalence approach to estimate the number of adults with NASH and the attributable economic and wellbeing costs. Given undiagnosed patients do not incur costs in the study, the probability of diagnosis is central to cost estimation. The analysis was based on a literature review, databases and consultation with clinical experts, economists and patient groups.

RESULTS

The proportion of adult NASH patients with a diagnosis ranged from 11.9% to 12.7% across countries, which increased to 38.8%-39.1% for advanced fibrosis (F3-F4 compensated cirrhosis). Total economic costs were €8548-19 546M. Of these, health system costs were €619-1292M. Total wellbeing costs were €41 536-90 379M. The majority of the undiagnosed population (87.3%-88.2% of total prevalence) was found to have early-stage NASH, which, left untreated, may progress to more resource consuming ESLD over time.

CONCLUSIONS

This study found that the majority of economic and wellbeing costs of NASH are experienced in late disease stages. Earlier diagnosis and care of NASH patients could reduce future healthcare costs.

Healthcare resource utilisation and sickness absence in newly diagnosed multiple myeloma patients who did not undergo autologous stem cell transplantation: Trends in Sweden with the changing treatment landscape

OBJECTIVES

The introduction of novel drugs has significantly improved outcomes for multiple myeloma (MM) patients. This study describes survival, healthcare resource utilisation and sickness absence in association with the changing MM treatment landscape over time, focussing on patients who did not undergo autologous stem cell transplantation (ASCT).

METHODS

Population-based, retrospective registry study in Sweden, where 7012 non-ASCT patients diagnosed between 2001 and 2015 were stratified into diagnosis periods 2001-2005 (n = 2053), 2006-2010 (n = 2372) and 2011-2015 (n = 2587).

RESULTS

Median survival increased from 2.5 to 3.4 years from 2001-2005 to 2011-2015. During the first 3 years of follow-up, patients diagnosed during 2011-2015 spent 29% and 12% less time in health care (55 days; inpatient admissions and outpatient visits) than patients diagnosed during 2001-2005 (78 days) and 2006-2010 (63 days), respectively. This was associated with less inpatient and more outpatient healthcare usage. Average 3-year sickness absence (362 days) was 31% and 12% less than for patients diagnosed during 2001-2005 (522 days) and 2006-2010 (410 days), respectively.

CONCLUSIONS

These findings of improved survival, reduced healthcare needs and greater productivity in non-ASCT MM patients with access to improved treatment practices and novel drugs provide important real-world cost-benefit insights for the continued development and introduction of treatments for MM.

The impact of fluticasone furoate/vilanterol on healthcare resource utilisation in the Salford Lung Study in chronic obstructive pulmonary disease

AIM

The Salford Lung Study (SLS) in chronic obstructive pulmonary disease (COPD) was a randomised controlled trial evaluating the effectiveness and safety of initiating fluticasone furoate/vilanterol (FF/VI) 100/25 µg versus continuing usual care (UC) in patients with COPD and a history of exacerbations. Here, we investigate the impact of initiating FF/VI on healthcare resource utilisation (HRU) in SLS COPD.

METHODS

HRU and interventions were determined from patients' electronic health records. Annual rates of on-treatment all-cause and COPD-related secondary care contacts (SCCs) and primary care contacts (PCCs) for FF/VI versus UC were analysed using a general linear model. Costs were derived from national data sources.

RESULTS

Least-squares (LS) mean annual rates of all-cause (9.81 versus 9.36) and COPD-related (1.57 versus 1.48) SCCs were similar for FF/VI and UC, as were rates of all-cause hospitalisations (0.87 versus 0.82). Mean duration of hospital stay/patient was 4.5 and 4.2 days, respectively. COPD-related SCC mean total cost/patient was £484 FF/VI and £475 UC. LS mean annual rates of all-cause PCCs were significantly higher for FF/VI (21.20 versus 18.88 UC; p < 0.001). LS mean annual rates of COPD-related PCCs were similar for FF/VI and UC (2.42 versus 2.46). All-cause PCC mean total cost/patient was £900 FF/VI versus £811 UC, but COPD-related PCC costs were similar (£116 versus £114). Direct COPD-related total medical costs/patient were significantly lower for FF/VI (LS geometric mean £806 versus £963 UC; p < 0.001).

DISCUSSION

In patients with COPD and exacerbation history, FF/VI may represent a less costly alternative to current therapies.GlaxoSmithKline plc. study HZC115151; ClinicalTrials.gov NCT01551758.The reviews of this paper are available via the supplemental material section.

Burden of pulmonary arterial hypertension in England: retrospective HES database analysis

BACKGROUND

The clinical and economic burden of pulmonary arterial hypertension (PAH) is poorly understood outside the United States. This retrospective database study describes the characteristics of patients with PAH in England, including their healthcare resource utilisation (HCRU) and associated costs.

METHODS

Data from 1 April 2012 to 31 March 2018 were obtained from the National Health Service (NHS) Digital Hospital Episode Statistics database, which provides full coverage of patient events occurring in NHS England hospitals. An adult patient cohort was defined using an algorithm incorporating pulmonary hypertension (PH) diagnosis codes, PAH-associated procedures, PH specialist centre visits and PAH-specific medications. HCRU included inpatient admissions, outpatient visits and Accident and Emergency (A&E) attendances. Associated costs, calculated using national tariffs inflation-adjusted to 2017, did not include PAH-specific drugs on the High Cost Drugs list.

RESULTS

The analysis cohort included 2527 patients (68.4% female; 63.6% aged ⩾50 years). Mean annual HCRU rates ranged from 2.9 to 3.2 for admissions (21-25% of patients had ⩾5 admissions), 9.4-10.3 for outpatient visits and 0.8-0.9 for A&E attendances. Costs from 2013 to 2017 totalled £43.2M (£33.9M admissions, £8.3M outpatient visits and £0.9M A&E attendances). From 2013 to 2017, mean cost per patient decreased 13% (from £4400 to £3833) for admissions and 13% (from £1031 to £896) for outpatient visits, but increased 52% (from £81 to £123) for A&E attendances.

CONCLUSION

PAH incurs a heavy economic burden on a per-patient basis, highlighting the need for improved treatment strategies able to reduce disease progression and hospitalisations.The reviews of this paper are available via the supplemental material section.

Healthcare resource utilisation associated with skeletal-related events in European patients with multiple myeloma: Results from a prospective, multinational, observational study

OBJECTIVES

Patients with multiple myeloma (MM) often experience debilitating skeletal-related events (SREs: pathologic fracture, radiation to bone [RB], surgery to bone [SB] or spinal cord compression [SCC]). This is the first comprehensive, prospective, observational analysis of healthcare resource utilisation (HRU), independently attributed to SREs by investigators, in patients with MM.

METHODS

Eligible patients had lytic bone lesions, life expectancy ≥6 months, Eastern Cooperative Oncology Group performance status ≤2 and ≥1 SRE in the 97 days before enrolment. Data were collected retrospectively for 97 days before enrolment and prospectively for 18-21 months.

RESULTS

Altogether, 153 patients were enrolled from Germany, Italy, Spain and the United Kingdom. Of the 281 observed SREs, 36.7% required inpatient stays (mean duration: 20.6 days per SRE [standard deviation (SD): 22.9]). SB and SCC were the SREs most likely to require stays (72.3% and 50.0% of SREs, respectively); SCC required the longest mean (SD) stay per event (40.5 [40.8] days). Overall, 179 SREs required outpatient visits; this was most likely for RB (74.8%) and least likely for non-vertebral fracture (50.0%).

CONCLUSIONS

All SREs were associated with substantial HRU; therefore, preventing SREs in MM will reduce the economic and resource burden on healthcare systems.

Cost of treatment in patients with metastatic soft tissue sarcoma who respond favourably to chemotherpy. The SArcoma treatment and Burden of Illness in North America and Europe (SABINE) study

Treatment of metastatic soft tissue sarcoma (mSTS) commonly includes multiple lines of chemotherapy, until a decline in performance status precludes further treatment. The primary objective of this study was to describe the lifetime healthcare resource utilisation and cost among mSTS patients with favourable response to chemotherapy. SABINE was a multi-centre (n = 25), multi-country (n = 9) retrospective chart review study of mSTS patients with favourable response to chemotherapy following 4 cycles. Healthcare resource utilisation was collected from first line until death or end of follow-up. Costs were analysed by health states (defined by treatment line, chemotherapy use and disease progression) and estimated by multiplying the mean weekly cost per health state by the expected number of weeks spent in each health state. Expected per-patient lifetime medical cost was €65 616 (95% CI: €51 454-€85 003); comprised of IV chemotherapy (31.7%), inpatient care (24.8%), concomitant medication (11.0%), oral chemotherapy (8.9%), outpatient visits (8.8%), radiotherapy (6.3%), hospice (4.0%), imaging (3.7%) and laboratory (0.7%). Weekly costs were 280-330% higher during chemotherapy treatment periods than off-chemotherapy, especially after disease progression. Per-patient costs were highest in the USA and lowest in the Netherlands and UK. The economic burden of mSTS is considerable and the amount of resources devoted to its treatment varies across countries.

Healthcare resource utilisation by critically ill older patients following an intensive care unit stay

AIMS AND OBJECTIVES

This study examines the utilisation of healthcare resources by critically ill older patients over one year following an intensive care unit stay.

BACKGROUND

Information on healthcare resource utilisation following intensive care unit treatment is essential during times of limited financial resources.

DESIGN

Prospective longitudinal nonrandomised study.

METHODS

Healthcare resource utilisation by critically ill older patients (≥65 years) was recorded during one year following treatment in a medical-surgical intensive care unit. Age-matched community-based participants served as comparison group. Data were collected at one-week following intensive care unit discharge/study recruitment and after 6 and 12 months. Recorded were length of stay, (re)admission to hospital or intensive care unit, general practitioner and medical specialist visits, rehabilitation program participation, medication use, discharge destination, home health care service use and level of dependence for activities of daily living.

RESULTS

One hundred and forty-five critically ill older patients and 146 age-matched participants were recruited into the study. Overall, critically ill older patients utilised more healthcare resources. After 6 and 12 months, they visited general practitioners six times more frequently, twice as many older patients took medications and only the intensive care unit group patients participated in rehabilitation programs (n = 99, 76%). The older patients were less likely to be hospitalised, very few transferred to nursing homes (n = 3, 2%), and only 7 (6%) continued to use home healthcare services 12 months following the intensive care unit stay.

CONCLUSIONS

Critically ill older patients utilise more healthcare resources following an intensive care unit stay, however, most are able to live at home with no or minimal assistance after one year.

RELEVANCE TO CLINICAL PRACTICE

Adequate healthcare resources, such as facilitated access to medical follow-up care, rehabilitation programs and home healthcare services, must be easily accessible for older patients following hospital discharge. Nurses need to be aware of the healthcare services available and advise patients accordingly.

Health resource utilisation associated with skeletal-related events in European patients with lung cancer: Α subgroup analysis from a prospective multinational study

Bone complications or skeletal-related events (SREs), typically defined as radiation to bone, pathological fractures, surgery to bone and spinal cord compression, occur frequently in patients with bone metastases. As the survival of patients with advanced lung cancer improves, preventing SREs is becoming increasingly clinically relevant. The aim of this analysis was to assess the impact of SREs on health resource utilisation (HRU) in European lung cancer patients with bone metastasis. This multinational, observational study included patients who had at least one SRE in the 97 days prior to enrolment, a life expectancy of ≥6 months and an Eastern Cooperative Oncology Group performance status of 0-2. Data on HRU were retrospectively collected for up to 97 days prior to enrolment with a planned prospective follow-up for up to 18-21 months. The HRU measures included the number and length of inpatient hospitalisations and the number of outpatient visits and procedures. The investigators determined whether each HRU was attributable to a SRE. In total, 135 patients with lung cancer, enrolled at centres in Germany, Italy, Spain and the United Kingdom, contributed 214 SREs to this analysis. The median length [quartile (Q)1, Q3] of follow-up ranged from 1.5 (0.7, 3.3) to 5.6 (2.0, 8.2) months across the countries. Overall, 41% of the SREs required an inpatient stay, with a median (Q1, Q3) duration of 19.0 (6.0, 28.0) days. Spinal cord compression and surgery to bone were the SRE types most frequently requiring inpatient stays. Radiation to bone was associated with the largest number of outpatient visits and procedures. All the SREs resulting from bone metastases in patients with lung cancer contribute considerably to HRU and efforts to minimise the incidence of bone complications in these patients through appropriate treatments may help reduce this burden.

Healthcare utilisation in patients with breast cancer or non-Hodgkin lymphoma who experienced febrile neutropenia in the Netherlands: a retrospective matched control study using the PHARMO database

Few data have been published on healthcare resource utilisation associated with chemotherapy-induced febrile neutropenia (FN) in Europe. Using the PHARMO record linkage system, we identified incident adult patients with a primary hospital discharge diagnosis of breast cancer (BC) or non-Hodgkin lymphoma (NHL) from 1998 to 2008. Patients who experienced FN were matched 1:2 non-FN reference patients. Of 1033 BC patients, 80 (8%) had FN and were matched with 160 reference patients; and of 486 NHL patients, 95 (20%) had FN and 89 were matched with 178 reference patients. Significantly more FN patients were hospitalised for any cause than reference patients: BC, 81% vs. 24% (OR 12.6; 95% CI 5.7-27.8); NHL, 82% vs. 44% (OR 6.7; 95% CI 3.3-13.9). Median length of all-cause hospitalisation stay was higher for FN patients: BC, 4.0 vs. 1.0 days; NHL, 8.5 vs. 1.8 days. The median (interquartile range) number of medication treatments was higher for FN patients: BC, 5.5 (4.0-7.5) vs. 2.0 (2.0-4.0); NHL, 8.0 (5.0-11.0) vs. 3.0 (2.0-4.0). In conclusion, FN in patients with BC or NHL had increased healthcare utilisation compared with non-FN patients; thus, efforts to reduce FN are warranted to reduce cost and improve outcomes.
