The impact of the COVID-19 pandemic on the provision & utilisation of primary health care services in Goma, Democratic Republic of the Congo, Kambia district, Sierra Leone & Masaka district, Uganda

INTRODUCTION

This study aimed to determine whether the COVID-19 pandemic had an impact on essential primary healthcare services at public primary healthcare facilities.

METHODS

The number of weekly consultations for antenatal care (ANC), outpatient (OPD), immunisations (EPI), family planning (FP) and HIV services, between January 2018 and December 2020, were collected from 25 facilities in Masaka district, Uganda, 21 in Goma, and 29 in Kambia district, Sierra Leone. Negative binomial regression models accounting for clustering and season were used to analyse changes in activity levels between 2018, 2019 and 2020.

RESULTS

In Goma, we found no change in OPD, EPI or ANC consultations, FP was 17% lower in March-July 2020 compared to 2019, but this recovered by December 2020. New diagnoses of HIV were 34% lower throughout 2020 compared to 2019. In Sierra Leone, compared to the same periods in 2019, facilities had 18-29% fewer OPD consultations throughout 2020, and 27% fewer DTP3 doses in March-July 2020. There was no evidence of differences in other services. In Uganda there were 20-35% fewer under-5 OPD consultations, 21-66% fewer MCV1 doses, and 48-51% fewer new diagnoses of HIV throughout 2020, compared to 2019. There was no difference in the number of HPV doses delivered.

CONCLUSIONS

The level of disruption varied across the different settings and qualitatively appeared to correlate with the strength of lockdown measures and reported attitudes towards the risk posed by COVID-19. Mitigation strategies such as health communications campaigns and outreach services may be important to limit the impact of lockdowns on primary healthcare services.

Optimising the use of physiotherapy resources after manipulation under anaesthetic for frozen shoulder

INTRODUCTION

Manipulation under anaesthetic (MUA) is a successful treatment for frozen shoulder (FS), and the recovery period and recurrence rates may be reduced by postoperative physiotherapy. This study evaluates two physiotherapy pathways for patients undergoing MUA for FS.

METHODS

Between 2016 and 2018, 248 age- and sex-matched patients presented to either a NHS secondary care upper limb service or the lead author's independent practice with a diagnosis of FS. The patients had differential access to postprocedure physiotherapy based on which service they presented to. In Group 1, physiotherapy advice only was given to the patient. In Group 2, supervised hydrotherapy and physiotherapy occurred postoperatively. Pre- and postprocedure Oxford Shoulder Scores (OSS) were collected for each group. Analysis of covariance (ANCOVA) was used to measure the effect of physiotherapy on postoperative OSS.

RESULTS

Group 2 showed a significantly greater improvement in postprocedure OSS when compared with Group 1 (18.2 vs 16.7) p<0.001). The estimated maximum effect of physiotherapy on postoperative OSS was an increase of 3.2.

CONCLUSION

Following MUA for FS, a statistically significant increase in OSS was detected in patients receiving postprocedure physiotherapy compared with advice alone. There was no difference in recurrence rates. The increase in OSS (3.2) is below the minimal clinically important difference, raising questions regarding the relative importance of postprocedure physiotherapy in a resource-limited environment.

1266 Digital Rectal Examination: Do You Still Put Your Foot in It If You Don’t Put Your Finger in It?

Introduction

Most surgical trainees are familiar with the aphorism ‘if you don’t put your finger in it, you put your foot in it’, with regards to digital rectal examination (DRE). This commonly taught maxim, attributed to Bailey and Love in their Short Practice of Surgery, was coined to highlight the folly of neglecting DRE in patients with histories suggestive of malignant anorectal pathology. However, data are lacking on the diagnostic yield of DRE for detecting anorectal cancer in patients with lower gastrointestinal bleeding (LGIB), whilst advances in biomarker and imaging technology beg the question: is there still a role for DRE in the assessment of patients with LGIB?

Method

We designed a clinical coding search strategy to identify all adult patients with acute LGIB referred to general surgery at a UK university hospital from January to July 2020. Electronic patient records were interrogated to identify history and examination findings, diagnoses and clinical outcomes.

Results

169 patients (median age 63 (16-94) years, 54.4% male) were identified, 74.6% (126/169) with bright red bleeding, 23.7% (40/169) with altered blood and 1.8% (3/169) with melaena. DRE was performed in 91.1% (154/169) of patients, identifying blood in 42.9% (66/154) of cases and suspicious lesions, which were subsequently confirmed as anorectal malignancy, in 1.3% (2/154).

Conclusions

DRE represents a possibly stigmatising and uncomfortable examination for patients and clinicians alike. These data support the utility of DRE in patients with LGIB and may inform the discussion at the bedside to facilitate the timely diagnosis of anorectal malignancy.

1419 Targeted Use of Physiotherapy Resources in The COVID Era: How Does Face to Face Physiotherapy Compare with Simple Advice Sheets After Manipulation Under Anaesthetic for Frozen Shoulder?

Introduction

This study compares two pathways for patients undergoing MUA for FS, one where physiotherapy advice is only given to the patient (Group 1), and the other where supervised hydrotherapy and physiotherapy occur post operatively (Group 2).

Method

A descriptive analysis of pre- and post-operative Oxford Shoulder Scores and change scores were performed. Analysis of covariance (ANCOVA) was used to measure the effect of physiotherapy on post-operative OSS, with pre-operative OSS as the only covariate.

Results

The results for post-operative OSS were significantly greater for Group 2 than for Group 1 (40.7 for NHS and 44.7 for private, improvement of 17.32 for NHS and 18.23 for Private). The effect of physiotherapy was significant (p &lt; 0.001). The estimated effect of physiotherapy on postoperative OSS was an increase of 3.2 (95% confidence interval 1.5 – 4.8).

Conclusions

We detected a statistically significant increase in post-operative OSS in patients treated for frozen shoulder with MUA + physiotherapy compared with patients receiving MUA plus advice alone. These results suggest that physiotherapy does confer a real benefit, however the increased OSS is below the clinically significant level. Therefore, in a resource poor environment, such as may exist during and after COVID in many health care systems, MUA plus physio advice alone gives an excellent outcome for the treatment of FS.

Spectral characterization of flash and high flux x-ray radiographic sources with a magnetic Compton spectrometer

In this work, we present a new analysis method applied to revitalize permanent magnet Compton spectrometers used to measure photon energy spectra in the MeV range. The inversion of the measured electron distribution to determine the original photon distribution is achieved via a method of consistent coupled radiation transport and magnetic field mapping of the input photon spectra to the measured electron distribution. The method of linear least squares was used to perform the unfolding of the electron distribution to the initial photon spectra, without any assumptions made regarding the electron distribution. We present an application of this method to data from a nominal 19.4 MeV flash radiographic source (the first axis of the Dual Axis Radiographic Hydro-Test Facility) capable of generating 500 R @ 1 m in ∼60 ns and a medical therapy source (a Scanditronix M22, Microtron) capable of variable energies with nominal endpoints of 6, 10, 15, and 20 MeV and an output of ∼1000-2000 R/min @ 1 m. The results provide agreement between the modeled and unfolded experimentally measured photon spectra as quantified by statistical tests, from 1.5 to 20 MeV. Experimental results are presented as well as a discussion of the novel MCNP6-based simulations and methods for reconstruction of the spectra.

18 Manipulation Under Anaesthetic for Frozen Shoulder: Does Post-Operative Supervised Physiotherapy Affect the Outcome?

Introduction

This study compares two pathways for patients undergoing MUA for FS, one where physiotherapy advice is only given to the patient (Group 1), and the other where supervised hydrotherapy and physiotherapy occur post operatively (Group 2).

Method

A descriptive analysis of pre- and post-operative Oxford Shoulder Scores and change scores were performed.

Analysis of covariance (ANCOVA) was used to measure the effect of physiotherapy on post-operative OSS, with pre-operative OSS as the only covariate.

Conclusions

We detected a statistically significant increase in post-operative OSS in patients treated for frozen shoulder with MUA + physiotherapy compared with patients receiving MUA plus advice alone. These results suggest that physiotherapy does confer a real benefit, however the increased OSS is below the clinically significant level. Therefore, in a resource poor environment, such as may exist after COVID in many health care systems, MUA plus physio advice alone gives an excellent outcome for the treatment of FS.

Does Time Since Injury and Time Spent in Physical Therapy Treatment Affect Outcomes for Concussion Patients?

Purpose

To evaluate the effects of: 1) time between injury and physical therapy treatment and 2) time spent in physical therapy, on concussion symptom resolution.

Methods

Retrospective data was obtained for 202 patients who sustained a concussion and were referred for physical therapy. Subjects were assigned to groups based on type of injury (sport-related or not), time elapsed between concussion and therapy (0-14 days, 15–30, 31–60, 61–120, 121–365), and months spent in treatment (1 thru 4). Pre- and post- treatment scores were compared for the following measures: Sport Concussion Assessment Tool (SCAT), Convergence Insufficiency Symptom Survey (CISS), Dizziness Handicap Inventory (DHI), and Modified Clinical Test of Sensory Interaction on Balance (mCTSIB) using ANOVAs, with a Bonferroni-corrected p-value of p<.005.

Results

There was no significant difference in outcomes for athletes vs. non-athletes on SCAT Symptom (p=.74) or Severity Score (p=.18), CISS (p=.52), DHI (p=.05), or mCTSIB (p=.10); in outcomes for time elapsed since injury on SCAT Symptom Score (p=.80), SCAT Symptom Severity Score (p=.97), CISS (p=.61), DHI (p=.65), mCTSIB (p=.13); or in outcomes for months in treatment on SCAT Symptom Score (p=.23), SCAT Symptom Severity Score (p=.04), CISS (p=.41), DHI (p=.37), mCTSIB (p=.50).

Conclusion

Post-therapeutic improvements were noted for athletes receiving post-concussive physical therapy. Type of injury, time between injury and treatment, and time spent in treatment did not differentiate treatment outcomes for those receiving physical therapy post-concussion.

Dynamics of tuberculosis in Wau, South Sudan during a period of armed conflict

BACKGROUND

South Sudan has endured decades of armed conflict, with the most recent in 2016. This has left the health system and infrastructure overstretched by a myriad of infectious diseases like tuberculosis. Our study aimed at quantitatively and qualitatively documenting TB dynamics and challenges with access to health care during a period of civil unrest in Wau.

MATERIALS & METHODS

A cross sectional study was carried out between January and February 2016 at Wau Teaching Hospital (WTH). Sputum was randomly collected from 207 of the 1035 TB suspects and analyzed using Ziehl-Neelsen (ZN) and Fluorescent Microscopy (FM), Culture, Capilia MTBC Neo, and DST. The laboratory results and questionnaire metadata were used for descriptive statistics, logistic regression in R version 3.4.2. These results were presented along with results from a qualitative assessment of the situation at WTH.

RESULTS

Of 207 TB suspects, 39 (18.8%) were positive on FM with bacilli growth on culture, later confirmed as Mycobacterium tuberculosis complex. Only 5.4% of the cases were resistant to Isoniazid. Age; 20-45 OR = 13 (95%CI = 2.4-25.6, p = 0.011), > 46 OR = 3 (95%CI = 0.5-58, p = 0.005) and raw milk consumption OR = 2.2 (95%CI = 0.37-42.48, p = 0.005) were associated with being TB positive. The qualitative evaluation reveals that gunfights in the surroundings of Wau influenced the number of patients attending WTH, with some travelling up to 545 km to seek medical attention.

CONCLUSION

We report a high prevalence of tuberculosis among patients who presented at WTH, with approximately 1 out of 5 individuals testing positive for tuberculosis. This is likely an underestimation given the challenges patients had to endure as they sought medical attention. Tuberculosis epidemiology is likely to be driven by individual and household factors, but further investigations are needed to fully understand the risk profile. The tools in use were adequate for TB diagnostics and we observed a remarkably low prevalence of drug resistance, a statistic that is worth preserving. We therefore call for action from all stakeholders.

Evaluation of Aintree LOSS, a community-based, multidisciplinary weight management service: outcomes and predictors of engagement

Aintree LOSS is a community-based, multidisciplinary weight management programme for patients with severe and complex obesity, focusing on a flexible and individualized service with follow-up for up to 2 years. We evaluated all 2472 patients referred to the service between October 2009 and 2013. Demographic data were recorded at baseline, with the Index of Multiple Deprivation (IMD) used to measure socioeconomic deprivation. Weight was recorded at each visit. Mean body mass index at baseline was 45.6 (standard deviation 6.8), and 58.9% of patients lived in areas in the most deprived decile nationally. Of 2315 appropriate referrals, 1249 (55.1%) attended >2 visits; mean final weight loss was 3.50 ± 8.55 kg, and 24.1% achieved ≥5% weight loss. Of the patients, 754 (33.3%) attended for over 6 months; mean final weight loss was 4.94 ± 10 kg, and 34% achieved 5% weight loss. Multivariate logistic regression analysis showed increasing age, residence in a less deprived area and sleep apnoea to be independently associated with attendance for >6 months, and there was a linear relationship between 6-month attendance and deprivation quintile. Year-on-year analyses showed improvement in engagement over time, coinciding with efforts to improve access to the service. This work shows a multidisciplinary, community-based weight loss programme prioritizing a fully flexible and individualized approach functioning effectively in real-world practice. Maintaining engagement remains a challenge in weight loss programmes, and our results suggest younger patients living in areas with greater deprivation should be a target for efforts to improve engagement.

Venous flaps for coverage of traumatic soft tissue defects of the hand: a systematic review

A PRISMA-guided systematic review was performed of all published cases that detail the use of venous flaps for soft tissue reconstruction of the hand following trauma. Outcome measures examined included flap survival rates, venous congestion, and return to theatre. Database searches were performed on Medline, Embase, AHMED, CINAHL. A total of 381 articles were identified. Data were extracted from 45 articles that met inclusion criteria. A total of 756 flaps were described and their data analysed. A total of 75% of flaps were arterialized and 25% were pure venous flaps. There was no difference in survival rate for arterialized or pure venous flaps. Unplanned return to theatre occurred in 5.3% due to flap compromise or necrosis. Early venous congestion was present in 60% of cases. Total early failure requiring re-operation occurred in 19 flaps (2.5%) of cases. Venous flaps offer a versatile and well-tolerated reconstructive option. Early venous congestion is common, but can be managed non-operatively.
