Primary care epidemiology: its scope and purpose

The implementation and evaluation of the Ontario COVID@Home Clinical Primary Care Pathway

BACKGROUND

The COVID@Home Clinical Care Pathway (the Pathway) was developed and implemented as an evidence-based remote monitoring clinical care pathway for the integrated management of coronavirus disease 2019 (COVID-19) in the province of Ontario, Canada. We examine its effectiveness and rapid large-scale implementation.

METHODS

Using a prospective longitudinal study design, we used electronic medical record clinical data, provider and patient surveys, web analytics, healthcare and provincial utilization, and government holdings data to evaluate reach, effectiveness, adoption, implementation, and maintenance outcomes, including patient mortality and health equity.

RESULTS

The Pathway was widely accessed (19 474 Ontario unique users), contributed 28 816 oxygen saturation monitors, and achieved coverage across income levels and geography. Two-thirds of patients had > 1 encounter, monitored for a median of 4 days (Range: 1-57). Fifty percent of patients had > 1 chronic condition. Patients receiving Pathway care were less likely to die by 0.44% (20/4556), two times lower compared to the total mortality of a population-based representative patient cohort over a parallel time period in Ontario of 0.86% (1820/212 326, P = .0023). Patients were very satisfied with their care, and felt care was accessible, safe, and clear. Providers were very satisfied with the Pathway resources and reported strengthened relationships across the health system.

CONCLUSIONS

Primary care (PC) rapidly implemented a clinical care pathway during the COVID-19 crisis. The Pathway demonstrated the beneficial role and effectiveness of PC when patients are provided with timely, accessible, and comprehensive care. Public health responses should explicitly collaborate with PC to address population health.

The landscape of medical care consumption in Israel: a nationwide population cross-sectional study

Background

The Ecology of medical care was first published in 1961. The graphical square model showed that 75% of the population in the US and England experience a feeling of illness during a given month, 25% seek medical help and only one percent are hospitalized. In 2001, Green and colleagues found the same findings despite the many changes that occurred over the past decades. The frequency of illness, the desire for assistance and the frequency of seeking and getting medical assistance may differ in different populations due to cultural, economic, social, demographic background and local Health policy. This work describes the ecology of medical care consumption in Israel for the first time and examines the socio-demographic effects on consumption.

Methods

This is a Nationwide cross-sectional study. A telephone survey was conducted among a representative sample of the adult population (> 15 years) in Israel. Subjective morbidity rate in the preceding month, the rate of those considering medical assistance and those who got assistance were calculated. Correlation between socio-demographic variables and patterns of morbidity and medical care consumption was examined using a t-test and chi square for continuous quantitative and categorical variables. Logistic regression was used for multivariate analysis.

Results

A total of 1862 people participated; 49.5% reported having symptoms in the previous month, 45% considered seeking medical advice, 35.2% sought out medical assistance and only 1.5% were hospitalized. The vast majority chose to contact their family physician (58%) and the primary care setting provided their needs in 80% of the cases; Subjective morbidity and medical care consumption differed significantly between Israeli Jews and Arabs. Gaps in the availability of medical services were observed as residents of the periphery forewent medical services significantly more than others (OR = 1.42, p = 0.026).

Conclusions

Subjective morbidity is less common in Israel than in other countries, but paradoxically consumption of medical services is higher. An Israeli who feels ill will usually consider receiving assistance and will indeed receive assistance in most cases. However, a greater tendency to forego medical services in the periphery indicates barriers and inequality in the provision of health services. Different cultural perceptions, lack of knowledge and low accessibility to medical services in the periphery probably contribute to the contrast shown between low consumption of medical services and high prevalence of chronic illness in Arab society. The prevailing preference for family medicine and its ability to deal with most requests for assistance suggest that strengthening family medicine in the periphery may reduce those barriers and inequalities.

General practitioner perspectives on factors that influence implementation of secondary care-initiated treatment in primary care: Exploring implementation beyond the context of a clinical trial

BACKGROUND

The Beta-blockers Or Placebo for Primary Prophylaxis of oesophageal varices (BOPPP) trial is a 3-year phase IV, multi-centre clinical trial of investigational medicinal product (CTIMP) that aims to determine the effectiveness of carvedilol in the prevention of variceal bleeding for small oesophageal varices in patients with cirrhosis. Early engagement of General Practitioners (GPs) in conversations about delivery of a potentially effective secondary care-initiated treatment in primary care provides insights for future implementation. The aim of this study was to understand the implementation of trial findings by exploring i) GP perspectives on factors that influence implementation beyond the context of the trial and ii) how dose titration and ongoing treatment with carvedilol is best delivered in primary care.

METHODS

This qualitative study was embedded within the BOPPP trial and was conducted alongside site opening. GP participants were purposively sampled and recruited from ten Clinical Commissioning Groups in England and three Health Boards across Wales. Semi-structured telephone individual interviews were conducted with GPs (n = 23) working in England and Wales. Data were analysed using reflexive thematic analysis.

FINDINGS

Five overarching themes were identified: i) primary care is best placed for oversight, ii) a shared approach led by secondary care, iii) empower the patient to take responsibility, iv) the need to go above and beyond and v) develop practice guidance. The focus on prevention, attention to holistic care, and existing and often long-standing relationships with patients provides an impetus for GP oversight. GPs spoke about the value of partnership working with secondary care and of prioritising patient-centred care and involving patients in taking responsibility for their own health. An agreed pathway of care, clear communication, and specific, accessible guidance on how to implement the proposed treatment strategy safely and effectively are important determinants in the success of implementation.

CONCLUSIONS

Our findings for implementing secondary care-initiated treatment in primary care are important to the specifics of the BOPPP trial but can also go some way in informing wider learning for other trials where work is shared across the primary-secondary care interface, and where findings will impact the primary care workload. We propose a systems research perspective for addressing implementation of CTIMP findings at the outset of research. The value of early stakeholder involvement is highlighted, and the need to consider complexity in terms of the interaction between the intervention and the context in which it is implemented is acknowledged.

Factors associated with the use of a public information system of dentist-prescribed antibiotics in Minas Gerais, Brazil

This article aims to investigate the association between socioeconomic factors, health care organizations, and the use of a management and monitoring system for the dispensing of antibiotics prescribed by dentists in public health services in Minas Gerais, Brazil. This is an ecological-epidemiological study that analyzed secondary data from the Integrated Pharmaceutical Care Management System (SIGAF) of the Department of Health of the state of MG, Brazil, in 2017. Thirteen independent variables were analyzed to assess their influence on municipal adherence to SIGAF system considering dental prescriptions of antibiotics. Descriptive statistical analyses were performed, and the Classification and Regression Tree technique was used to identify the municipal variables associated with the outcome. A total of 57,279 antibiotic courses prescribed by dentists and recorded in SIGAF were examined. Socioeconomic factors were not associated with the use of SIGAF to record these prescriptions. Oral healthcare coverage was positively associated with the use of SIGAF for the dispensing of antibiotics prescribed by dentists. Dental Specialties Center were negatively associated with the outcome. Municipalities with high oral healthcare coverage and those without a Dental Specialties Center were more likely to use SIGAF.

Referral pattern of oral and maxillofacial surgery cases in Sudan: A retrospective age-and sex-specific analysis of 3,478 patients over four years

Oral and maxillofacial surgery (OMFS) is a specialty widening in its scope. An objective analysis of the referral pattern can provide essential information to improve healthcare. This four-year retrospective study was implemented in Khartoum Teaching Dental Hospital. Data (age, sex, diagnosis, and type of treatment) were collected from patient records. Disease frequency, as well as the effect of sex and age, were analyzed for each group. The frequency of treatment types was also assessed. Data were collected from a total of 3,478 patients over the four-year study period. There was a male predominance with the third decade of life being the most common age group. Pathological diseases were the most common (37%) reason for referral, followed by trauma (31%). Temporomandibular joint (TMJ) disorders and dentoalveolar extraction were the least frequently observed. Open reduction and internal fixation (ORIF) was the most commonly performed procedure (28%). These data represent the epidemiology of oral and maxillofacial diseases in Sudan. Given that the third decade of life is the most represented age group, it is beneficial to learn the long-term consequences of these diseases in these young patients and to use modern surgical techniques to improve their lives.

Integrated CARE: Adaptation of Child-Adult Relationship Enhancement (CARE) Model for Use in Integrated Behavioral Pediatric Care

The authors adapted the established Child-Adult Relationship Enhancement (CARE) interaction model for use in integrated behavioral health clinics. CARE was modified for delivery in the examination room, during routine primary care visits. Adopting a real-world implementation approach, clinical social workers were trained in the new model-IntegratedCARE-and provided the brief, 3-session treatment to 30 different parent-child dyads. Measurements included the Parental Stress Index-4 Short Form (PSI 4-SF), the Eyberg Childhood Behavior Inventory (ECBI), and the Therapy Attitude Inventory (TAI). There was a statistically significant mean score decrease on the both subscales of the ECBI at pre- and posttreatment. Scores on the TAI indicated that participants were satisfied with the treatment. Attrition rates were somewhat lower than similar studies. Findings indicate the IntegratedCARE model is feasible for sustainable delivery by trained behavioral health professionals in primary care.

The Role of Organizational Factors and Human Resources in the Provision of Dental Prosthesis in Primary Dental Care in Brazil

This study aimed to investigate factors associated with dental prosthesis procedures by oral health teams (OHTs) in the Brazilian primary health care in 2013–2014, who participated in the National Program for Improving Access and Quality of Primary Health Care (PMAQ-AB). This is an analytical cross-sectional study using a questionnaire with dichotomous questions applied in 18,114 OHTs. The dependent variable studied was making any type of prosthesis (removable or fixed). Independent variables involved issues related to human resources and health service management. Data were submitted to simple and multiple binary logistic regression with odds ratio calculation, 95% confidence intervals, and p-values. Most OHTs (57%) do not perform any dental prosthesis. The teams that are more likely to perform dental prostheses have human resources-related characteristics, such as professionals admitted through public examinations (OR 1.25, 95% CI 1.14–1.36) and those involved in permanent education (OR 1.13, 95% CI 1.02–1.26). Moreover, OHTs with a more organized work process and that receive more significant support from municipal management are more likely to perform dental prostheses (p < 0.05). The oral health teams which tended to provide the most dental prostheses to benefit patients were; hired as civil servants, had a municipal career plan, involved all members of the oral health team, and trained undergraduate dental students from outreach programs. Better organizational support and improved work incentives may be needed to get the majority of oral health teams to start providing dental prostheses to their patients.

Utilization of Outpatient Eye Care Services in Taiwan: A Nationwide Population Study

Introduction

A study based on the Taiwanese National Health Insurance Research Database (NHIRD) to reveal the ocular diseases landscape.

Materials and Methods

This study comprised all ophthalmological outpatient patient visits (n = 6,341,266) in the Taiwanese longitudinal NHIRD 2000. Descriptive analytics based on 15 disease categories of ICD-9-CM and 10 tiers of age categories was performed with SAS for Windows 9.3 (SAS Institute, Inc., Cary, NC, U.S.A.).

Results

The average frequency of visits was 0.7 visits per year. The mean age was 36.2 years old. Bimodal peak of visits in the first, second, and eighth decade of life was revealed. Conjunctiva is the most dominant disease category throughout life while different categories play major roles in each decade of life. The most frequent disease code of each category was listed.

Discussion

The bimodal peak of visits revealed the age group of the most prominent ocular disease burden. Peak in school age population can be partially explained by the nationwide vision screening program, while aging accounts for the lens disorder and glaucoma of the senile peak. The disease category frequency variation among age categories reflects the development and aging of the eye. The most frequent disease codes of each category highlight disease of importance for primary practitioners and ophthalmologists.

Conclusion

Taiwanese longitudinal NHIRD was used to reveal the ophthalmological disease landscape. The epidemiological insight, while limited in clinical presentation and economic impact, enables physicians and policy makers to improve the overall vision health of the population.

What Has Changed in the Dental Prosthesis Procedures in Primary Health Care In Brazil?

The study aimed to identify the changes in the provision of dental prosthetics procedures in the Brazilian primary care. Secondary data from the Brazilian "National Programme for Improving Access and Quality of Primary Care" was assessed and three similar questions related to dental prostheses execution that were answered by the same 9,698 oral health teams, in 2011/2012 and 2013/2014, were compared. There was a 4.3% increase in the number of teams that identified individuals with prosthetic needs; a 0.8% increase in the number of teams that performed impression for prosthetic purposes; and the number of teams that reported performing dental prostheses consultations increased by 0.6%. Overall, there was a small modification in the number of teams that provided dental prosthesis procedures in Brazil.

Transforming cancer outcomes in England: earlier and faster diagnoses, pathways to success, and empowering alliances

Cancer outcomes and patient experience in England have never been better but survival remains worse than in comparable countries. Differences in stage at diagnosis and, to a lesser extent, access to optimal treatments are likely to be the most important factors. The national cancer plan emphasizes earlier and faster diagnosis and the creation of cancer alliances providing strategic leadership and coordination. Earlier diagnosis is being promoted by national awareness campaigns designed to overcome fatalism and perceived barriers to consulting a general practitioner as well as improvements to existing screening programs and the introduction of more targeted screening such as Lung Health Checks. These are supported by local social marketing campaigns in which trained volunteers support and advise others about cancer and cancer care. The epidemiology of symptoms in general practice provides an organizing framework for cancer diagnostic pathways. Alliances are implementing a broader model of cancer diagnostic clinics at a larger scale taking into account the different needs of patients with 1) obvious alert symptoms, 2) low risk but not no risk symptoms, and 3) serious but not specific symptoms. Faster diagnosis is being promoted by the introduction of a Faster Diagnosis Standard requiring patients are given a diagnosis of cancer or have it ruled out within 28 days of referral. The three cancer alliances forming the National Cancer Vanguard together with NHS England are publishing clinically led evidence-based Timed Diagnostic Pathways which show how the drastic changes needed can be achieved. Cancer alliances have been successful in developing clinical cancer pathways which need support by improved commissioning and regulatory approaches which align clinical pathways with financial and performance ratings. Clinical leadership has been essential but further focus is needed on making sure that performance and regulatory approaches give proper attention and encouragement to earlier and faster diagnosis.

The dire need for primary care specialization in India: Concerns and challenges

Primary health care is an evidence-based priority, but it is still inadequately supported in many countries. Ironically, on one hand, India is a popular destination for medical tourism due to the affordability of high quality of health care and, on the other hand, ill health and health care are the main reasons for becoming poor through medical poverty traps. Surprisingly, this is despite the fact that India was committed to 'Health for All by 2000' in the past, and is committed to 'Universal Health Coverage' by 2022! Clearly, these commitments are destined to fail unless something is done to improve the present state of affairs. This study argues for the need to develop primary care as a specialization in India as a remedial measure to reform its health care in order to truly commit to the commitments. Three critical issues for this specialization are discussed in this review: (1) The dynamic and distinct nature of primary care as opposed to other medical specializations, (2) the intersection of primary care and public health which can be facilitated by such a specialization, and (3) research in primary care including the development of screening and referral tools for early diagnosis of cancers, researches for evidence-based interventions via health programs, and primary care epidemiology. Despite the potential challenges and difficulties, India is a country in dire need for primary care specialization. India's experience in providing low-cost and high quality healthcare for medical tourism presages a more cost-effective and efficient primary care with due attention and specialization.

Catchments of general practice in different countries--a literature review

The purpose of this paper is to review the current research on catchment areas of private general practices in different developed countries because healthcare reform, including primary health care, has featured prominently as an important political issue in a number of developed countries. The debates around health reform have had a significant health geographic focus.

Conceptually, GP catchments describe the distribution, composition and profile of patients who access a general practitioner or a general practice (i.e. a site or facility comprising one or more general practitioners). Therefore, GP catchments provide important information into the geographic variation of access rates, utilisation of services and health outcomes by all of the population or different population groups in a defined area or aggregated area.

This review highlights a wide range of diversity in the literature as to how GP catchments can be described, the indicators and measures used to frame the scale of catchments. Patient access to general practice health care services should be considered from a range of locational concepts, and not necessarily constrained by their place of residence. An analysis of catchment patterns of general practitioners should be considered as dynamic and multi-perspective. Geographic information systems provide opportunities to contribute valuable methodologies to study these relationships. However, researchers acknowledge that a conceptual framework for the analysis of GP catchments requires access to real world data. Recent studies have shown promising developments in the use of real world data, especially from studies in the UK.

Understanding the catchment profiles of individual GP surgeries is important if governments are serious about patient choice being a key part of proposed primary health reforms. Future health planning should incorporate models of GP catchments as planning tools, at the micro level as well as the macro level, to assist policies on the allocation of resources so that opportunities for good health outcomes for all groups within society, especially those who have been systematically denied equitable access, are maximised.

Mothers' antenatal depression and their children's antisocial outcomes

Interviews of 120 British adolescents and their parents (80% of a random sample of antenatal patients drawn from a representative urban population and followed longitudinally) revealed that 40 (33%) had been arrested and/or had a diagnosis of DSM-IV conduct disorder by 16 years of age; of those, 18 (45%) had committed violent acts. Depression in pregnancy significantly predicted violence in adolescence, even after controlling for the family environment, the child's later exposure to maternal depression, the mother's smoking and drinking during pregnancy, and parents' antisocial behavior. Mothers with a history of conduct problems were at elevated risk to become depressed in pregnancy, and the offspring of depressed women had a greater chance of becoming violent by age 16.

Marital status, feeling depressed and self-rated health in rural female primary care patients

OBJECTIVE

To determine whether marital status and self-assessed mental health are independent risk factors for poor self-rated overall health among female primary care patients.

DESIGN

We conducted a cross-sectional survey of family medicine patients treated in a clinic in rural Minnesota. Complete responses were obtained from 723 women. Self-ratings of mental health, demographics and symptoms were used to predict self-rated overall health.

RESULTS

Women who were single, divorced or otherwise not married, or widowed had lower odds of good self-rated overall health (OR = 0.39, P = 0.004) compared with married women. Women who were 65 years of age and over (OR = 0.31, P = 0.017), women who rated themselves as depressed (OR = 0.54, P = 0.029), and women who reported more physical symptoms (OR = 0.78, P = 0.000) also were less likely to have good health, compared with younger women, women who did not feel depressed, and women with fewer physical symptoms, respectively. Education was not independently related to health in this sample. Worry was related to health in the univariate analysis but not after controlling for self-assessed depression.

CONCLUSIONS

In order to improve overall health among rural women seen in primary care settings, special attention may need to be directed at women who are single, are older, report more physical symptoms, and feel depressed. Programmes should include self-help materials, support groups and counselling services addressing social isolation, employment and financial hardship.

Health and Quality of Life Associated With Chronic Pain of Predominantly Neuropathic Origin in the Community

OBJECTIVES

To assess the health and quality of life associated with chronic pain of predominantly neuropathic origin (POPNO) on health and daily activity in the general population.

METHODS

The Self-complete Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) questionnaire, recently validated for identifying pain of predominantly neuropathic origin, was sent to 6000 adults identified from general practices in the United Kingdom, along with chronic pain identification and severity questions, the Brief Pain Inventory (BPI), the Neuropathic Pain Scale, and the SF-36 general health questionnaire.

RESULTS

With a corrected response rate of 52%, 3 groups of respondents were identified: those without chronic pain ("No Chronic Pain" group, n=1537); those with chronic pain who were S-LANSS positive indicating the presence of POPNO ("Chronic POPNO" group, n =241); and those with chronic pain who were S-LANSS negative ["Chronic Pain (non-POPNO)" group, n=1179]. The chronic POPNO group reported higher pain severity and had significantly poorer scores for all interference items of the BPI than those with chronic pain (non-POPNO). Mean scores from the Neuropathic Pain Scale were also significantly higher for the Chronic POPNO group. There were significant differences between the groups in all domains of the SF-36, with the Chronic POPNO group reporting the worst health. After adjusting for pain severity, age, and sex, the chronic POPNO group was still found to have poorer scores than the other Chronic Pain (non-POPNO) group in all domains of the SF-36 and all interference items in the BPI, indicating poorer health and greater disability.

DISCUSSION

This study confirms the importance of identifying neuropathic pain in the community, and the need for multidimensional management strategies that address all aspects of health.

Increasing incidence of skin disorders in children? A comparison between 1987 and 2001

Background

The increasing proportion of skin diseases encountered in general practice represents a substantial part of morbidity in children. Only limited information is available about the frequency of specific skin diseases. We aimed to compare incidence rates of skin diseases in children in general practice between 1987 and 2001.

Methods

We used data on all children aged 0–17 years derived from two consecutive surveys performed in Dutch general practice in 1987 and 2001. Both surveys concerned a longitudinal registration of GP consultations over 12 months. Each disease episode was coded according to the International Classification of Primary Care. Incidence rates of separate skin diseases were calculated by dividing all new episodes for each distinct ICPC code by the average study population at risk. Data were stratified for socio-demographic characteristics.

Results

The incidence rate of all skin diseases combined in general practice decreased between 1987 and 2001. Among infants the incidence rate increased. Girls presented more skin diseases to the GP. In the southern part of the Netherlands children consulted their GP more often for skin diseases compared to the northern part. Children of non-Western immigrants presented relatively more skin diseases to the GP. In general practice incidence rates of specific skin diseases such as impetigo, dermatophytosis and atopic dermatitis increased in 2001, whereas warts, contact dermatitis and skin injuries decreased.

Conclusion

The overall incidence rate of all skin diseases combined in general practice decreased whereas the incidence rates of bacterial, mycotic and atopic skin diseases increased.
