Profile of respiratory problems in patients presenting to a referral pulmonary clinic

Improving primary care access to respirologists using eConsult

BACKGROUND

Patients and primary care providers (PCPs) can experience frustration about poor access to specialist care. The Champlain Building Access to Specialists through eConsultation (BASETM) is a secure online platform that allows PCPs to ask a clinical question to 142 different specialty groups. The specialist is expected to respond within 7 days.

METHODS

This is a retrospective review of the Champlain BASETM respirology eConsults from January 2017 to December 2018. The eConsults were categorized by types of questions asked by the referring provider and by the clinical content of the referral. Specialists' response time and time spent answering the clinical question were analyzed. Referring providers' close-out surveys were reviewed to assess the impact of the respirology eConsult service on traditional referral rates and clinical course of action.

RESULTS

Of the 26 679 cases submitted to the Champlain BASE TM eConsult service, 268 were respirology cases (1%). 91% were sent by family physicians and 9% by nurse practitioners. The median time to respond by specialists was 0.8 days, and the median time billed by specialists was 20 min. The most common topics were pulmonary nodules and masses (16.4%), cough (10.4%), infective problems (8.6%), chronic obstructive pulmonary disease (8.6%) and dyspnea Not Yet Diagnosed (NYD) (7.8%). The most common types of questions asked by PCP were related to investigations warranted (43.1% of cases), general management (17.5%), monitoring (12.6%), need for a respirology referral (12.3%) and drug of choice (6.3%). In 23% of cases, the PCP indicated they were planning to refer the patient for an in-person consultation but no longer needed to after receiving the eConsult advice (avoided referrals). On the other hand, in 13% of cases, the PCP was not going to refer but did after the eConsult (prompted referrals). The eConsult led to a new or additional clinical course of action by the PCP in 49% of cases. In 51% of cases, the PCP suggested the clinical topic would be well suited to a CME event.

CONCLUSIONS

Participation in eConsult services can improve timely access to respirologists while potentially avoiding clinic visits and significantly impacting referring PCPs clinical course of action. Using the most common clinical topics and types of questions for CME planning should be considered. Future research may include a cost analysis and provider perspectives on the role of eConsult in respirology care.

Trends, patterns and causes of respiratory disease mortality among inpatients in Tanzania, 2006-2015

OBJECTIVE

To determine the causes, patterns and trends of respiratory diseases-related deaths in hospitals of Tanzania 2006-2015.

METHODS

Retrospective study involving 39 hospitals. Medical records of patients who died in hospital were retrieved, reviewed and analysed. Sources of data were hospital admission registers, death registers and International Classification of Diseases report forms. Information on demographic characteristics, date of death, the immediate underlying cause of death and co-morbid conditions was collected.

RESULTS

Of the 247 976 deaths reported during the 10-year period, respiratory diseases accounted for 12.92% (n = 32 042). The majority of the respiratory mortality was reported among males (55.9%). Overall median age at death was 31 years with an interquartile range (IQR) of 1-47. Median age at death was significantly higher among males (35 years) than females (28 years) (P < 0.0001). Most deaths (37.8%) occurred in eastern Tanzania. About one-third (31.3%) of all respiratory mortality was reported among under-five children, being among girls than boys (34.3% vs. 28.9%, χ²  = 10.3, P < 0.0001). Adolescent and young adult females (15-29 years) had higher age-standardised mortality rates per 100 000 due respiratory diseases than males. Pneumonia (n = 16 639; 51.9%) and pulmonary tuberculosis (n = 9687; 30.2%) accounted for the majority of deaths due to respiratory diseases. Significantly more females (n = 7665; 54.5%) than males died from pneumonia (n = 8878; 49.8%; χ²  = 8.5, P < 0.0001). By contrast, significantly more males (n = 6024; 34%) than females (n = 3596; 26%; χ²  = 15.5, P < 0.0001) died of tuberculosis. The proportion of death due to tuberculosis declined from 32.8% in 2006-2010 to 7.9% in 2011-2015. However, there was a significant increase in the proportion of death due to pneumonia from 49.6% in 2006-2010 to 53.4% in 2011-2015. Co-morbid conditions contributed to 9.1% (2871/31 628) of all deaths due to respiratory diseases. The most common co-morbid condition was HIV which accounted for 1735 (60.4%) deaths and was more common among males (60.8%; n = 957) than among females (59.7%; n = 764).

CONCLUSIONS

Respiratory diseases account for a substantial proportion of all causes of hospital death in Tanzania. Pneumonia and tuberculosis contribute to more than three quarters of all deaths due to respiratory diseases. Since most major respiratory illnesses are avoidable, it is important to strengthen the capacity of the health delivery system in managing cases of respiratory diseases.

Cough of more than two weeks - Time to think beyond pulmonary TB

BACKGROUND

Cough of more than two weeks has become sine quo non with pulmonary tuberculosis (PTB) in a developing country like India. The causes may be different in patients reporting to respiratory OPD vis a vis general OPD.

AIMS AND OBJECTIVES

To study the prevalence of PTB and causes of cough other than PTB among respiratory OPD attendees with cough of more than two weeks duration.

METHODS

A cross sectional study was carried out over two years in respiratory OPD of a tertiary care chest center of Indian armed forces. Of the 13,004 patients, 505 non HIV PTB suspects were included. Patients with definitive diagnosis of chronic cough were excluded. Efforts were made to establish diagnosis of pulmonary TB using clinical, microbiological and radiological features. However, patients were also subjected to further evaluation (spirometry, bronchoscopy, CECT) based on clinical features, radiological and lab profile to establish definitive diagnosis.

RESULTS

Out of the 505 patients, 10.5% patients had smear positive pulmonary TB, 13.5% smear negative PTB, bronchial asthma (24%), COPD (9.3%), diffuse parenchymal lung diseases (DPLD's) (12.5%), bronchiectasis (6.3%), lung cancer (5.3%) and congestive cardiac failure (4.2%).

CONCLUSION

Though prevalence of PTB in the study correlated well with the national statistics, but a significant number of patients had other causes of chronic cough, especially, obstructive airway diseases and DPLDs. Thus, there is a need to spread awareness regarding other causes of chronic cough and all efforts should be made to establish alternate diagnosis especially in patients who do not conclusively have PTB.

Respiratory diseases morbidity and mortality among adults attending a tertiary hospital in Nigeria

OBJECTIVE

To determine the morbidity and mortality related to respiratory diseases among adults attending a tertiary-care hospital in Nigeria.

METHODS

We carried out a retrospective study of 183 adult patients (> 15 years of age), diagnosed with respiratory diseases between November of 2006 and October of 2008 at the Federal Medical Centre in Ido-Ekiti, Nigeria.

RESULTS

Of the 183 patients enrolled in the study, 78 (42.6%) were male and 105 (57.4%) were female, the male: female ratio being 1:1.4. Respiratory diseases were predominant in the 25-44 year age bracket (37.2%) and lower socioeconomic class (81.4%). Pulmonary TB was the leading cause of morbidity (in 42.1%), followed by asthma (in 17.5%) and pneumonia (in 15.3%). Lung cancer was uncommon (in only 0.6%). Pulmonary TB was the leading cause of hospitalization for respiratory disease (in 32%). Pulmonary TB, asthma, pneumonia and pleural pathologies were more common in women, whereas COPD was more common in men. The most common comorbidity was HIV infection (in 11.5%). The overall mean length of hospital stay was 14 days. Overall mortality was 8.7%; 50% of the deaths were attributed to pulmonary TB, 25% were attributed to pleural disease, 12.5% were attributed to pneumonia, and 6.25% were attributed to acute exacerbation of COPD. Mortality was higher in women and in the 25-44 year age bracket.

CONCLUSIONS

Pulmonary TB, asthma and pneumonia were the leading causes of respiratory disease-related morbidity. Pulmonary TB was the leading cause of respiratory disease-related mortality among the adult Nigerians evaluated. Therefore, these conditions should be given higher priority in patient care. In addition, antiretroviral therapy should be readily accessible and affordable to HIV-infected individuals.
